UTOMOBILE'STEEBING-W'HEEL LOCK.

Applicntion Ille'd llray o, 191?.

To all whom z't may concern:

Be it known that I, CLAUDE E. MENTZER, a citizen of the United States, and resident 0f Des Moines, in thc county of Polk end State of Iowa, have invented a certain new sind useful Automobile-Steering-Wheel Lock, of which the following is a, specication.

The object` of my invention is to provide an automobile :steering wheel look of simple, durable and inexpensive construction.

More purtioulely it vis my object 'to g vide a device whcicb)v 'the steering wheel an automobile muy he readily .lgifsloiflimei the steering poet column or Shell, .sitio unfiting mechanism .including :nenne wherein fi key may he given a. full turn oi? heli t "n fox` operating the mechanism 'for permitting the key to be Withdrawn after the locking mechenism has bei'znoperetecl.

lith these and other objects in View, my invention consists in the construction, an rangement and combination ot' `the various peints of the device, whereby the objects oonteniplated are attained, hereinafter more fully set forth, pointed out in my claim imei illustrated in the accompanying drawings, in which:

Figure l shows side elevation of ou en toniohilo steering' wheel eouippeiil with lock embodying niy invention part ol the huh of the wheel. and the lock. n'iechnnie'fn he ing Shown in vertical, cross eect'ioin Fig i4 Shows u verticul, control, eectionei View through the huh of the wheel will the locking mechenisi'n, the :steering Shaft and. part of the mechanism being' broken away, to more clearly show the parte.

Fig. 3 shows on inverted, horizonul. tional view taken on the lino 3---3 of 'i i' Fig. 4: shows en inverted, horizontal, tional View taken on the line l--l o. Fig. 2, an.

Fig. 5 shows u. vertical, Sectional View teken on the line 5-5 of Fig. .2.

In the accompanying drawings, l have used the reference numeral l() th ini-lione generally the central, .hollow steering shaft of an laiutornooile which is received in the hollow sleeve of the post 1l.

The steering wheel 12 is provided with the hollow hub 13 having e hollow cylindrical downward extension 14, which receives the upper end of the sleeve 11.

f Mounted 0n the shaft 10 is o Sleeve l held in position by a key 17, sind having in its lower end e laterally extending unnuhn le plovitlesl :it its .loi/vm: cud with Specification of Letters latent.

vertically slidalulo nn annular ring 20, havin fece n serien of teeth 2l n opted in one )posi-fW tion of the ringQO to count with the teeth 19 Aon the liangc 18.

Secured to the ring u series of upw erdly above the flange is 20 on opposite sides thereof are upwardly extending Slide hars 22, $5

Screws extend through 'the Slots 26 und nllord means whereby when the hund 24 is rotated, the locking hers 22 will be slid 8U vertically.

The huh 13 is provided with a lateral vextension 29 forming u housing for a lock 30, having :i rotating key cylin er or plug 3l.

The lool; 30 may be of 'foi' ii'ietainoc, tho pin tumbler type. The wy cylinder 3l hue e lacy hole elot and. u laterally' extcnilinw lug 33.

iiolulziily in .loosely mounted on the cyliisalel 3l above the lug 33 is :i tpluto 0r the like 34.- .in which is mount/ed u. pin 35 which meende downwardly. Pivot/eil to the lower enti of the ,om 35 ie o lini iti extending through u hoiimnitel-lxy, fjeloxigntoil slot in the Well of the huh L3, es @chown in Figsn .'12 und 3.

The inner enrl of the link 36 is pivoted to u. ln'eol-iot il? on thc lower portion of the ol-nil (lo I he upper en. oi the huh :i ':oieipluie 38 which is hold in position by u my 3'.) ,screwed on lo the oppio end of the :slsnf ll).

'lliic )iuris horclolufove described, ure S0 :ii-:onheil that lowered position, the teeth 2l engage the teeth 19 und the steering column or sleeve 11, is lii'mly locked to the hub of the steering wheel hv the following moons, namely, the pin i7, the ring flange 18, the teeth 21, the ring 2U the n1e1nhere Q2 und the .extension 14 and` huh 13.

on its lower sur- B0 :nl ennuler lmnil lo which 7g3 any suitable type euch, 35

key so 13 is placed 10o wwn the ring1r ZU is in its 105 1G, the teeth 19 on the v110 Assume that the band Q4. is in its raised position, es shown in Fig. 2, andthat it is desired to lower the ring 2i), causing its teeth to engage the teeth 19, then the key L10 is ineerted into the key hole 32 and turned for causing the lug to engage the pin 35 for thereby moving the link 3G and rotating the band 24.

The rotation of the bend 24E causes it to travel on the screws 25 and slide them down Wax-div carrying with it the locking bars 22 and tile ring 20 oonneed tlu-n'ewlth, until the teeth 21 engage the teeth 19. The mtu 'tion of the band is comparatively Slight, but

on account of the arrangemmit of the lug 33 and the pin 35, it will be seen that .a full turn may be given to the key on each locking or unlockincr operation of the device, so as to l crmit tiie key to be readily and easily wit drawn after each operation.

Some changes may be made in the construction, and arrangement of the parts of my improved lockingr device without departing from the essential spirit and purpose of my invention, and it is my intention to cover by the claim to be issued upon the patent hereof, any such changes which may be rem sonably included within the scope of my claim.

1 claimas my invention:

In e device of the class described, the combination of two members, one of' said members being capable of movement with relation to the other, a lock element on one of said members, n coacting lock element slidably mounted on the other of said members, a tumbler lock mounted adjacent t0 said last described locking element including a'key cylinder or plug, a laterally extending arm on said plug, a rotary member, means for operatively connecting said rotary member and said second described lock member whereby rotation of the rotary member imparts movement to thel saidsecond locking member, a collar mounted on said plu u pin extending away from seid collar, a, link pivotcd on seid pin, seid link being o eretively connected `with said rotary mem er, said pin being arranged in the path of said Des Moines, iowa, A ril 28, 1917.
